element and Mesh Variation
element and Mesh Variation
(OP)
Can anyone explain briefly why different types of meshi patterns like shell,solid,hex,tria or ortho tria used for a single analysis?
Not a single time but for the same analysis there are many different mesh patterns being used. why is it so ?

RE: element and Mesh Variation
you're also using the phrase "mesh patterns" in a way i've never heard before. in my experience the term refers more to the appearance of the mesh, the density of the nodes, rather than the elements used.
RE: element and Mesh Variation
We use shell and solid but the thing is that why the need for different elements.. i.e. for a single durability analysis we can employ diifernt global sized mesh with varying elements like shell as wll as tet or ortho tria mesh.. why is it is so nad how it will have its effect on the analysis?
Also i am a novice in this field which i have had my hands till modelling only.. so let me know your thoughts about this !!
RE: element and Mesh Variation
If u want to analyse a solid pole with a thin disc attaced to it....
SO u have to use Solid elements 4 meshing the pole. and Shell elements for the THin disc
Element selection depends on the geometry and the behaviour of the structure to be anlysied
RE: element and Mesh Variation
if you want to fill the volumen enclosed by a suface, now you're talking a 3D shape, and you have to use 3D (ie solid) elements.
it's a different question if you're asking tri or quad. Generally quads are better than tri, they suit the math better. but quads can have difficulty mapping surfaces (4 points don't make a flat plane); tris can mapp any surface (3 points define a flat surface) but their results can be "suspect".
